INSTALLATION
PROCEDURE
1. INSTALL REAR ENGINE MOUNTING INSULATOR
(a) Engage the clamp and install the vacuum hose to the rear engine mounting insulator.
(b) Install the wire harness clamp bracket to the rear engine mounting insulator with the bolt.
Torque:
10 N·m {102 kgf·cm, 7 ft·lbf}
(c) Align the hole of the rear engine mounting insulator with the protrusion of the rear engine mounting bracket, slide the rear engine mounting insulator onto the rear engine mounting bracket to align the holes and install the rear engine mounting insulator with the bolt. Torque: 72 N·m {734 kgf·cm, 53 ft·lbf} |

5. INSPECT REAR ENGINE MOUNTING INSULATOR
(a) Disengage the clamp to separate the vacuum hose. |
|
(b) Disconnect the vacuum hose.
(c) Using a vacuum pump, apply vacuum of 80 kPa (600 mmHg, 23.6 in.Hg) and wait for 1 minute. |
|
(d) Check that there is no change in the needle movement of the vacuum pump gauge.
OK:
Vacuum pressure holds.
(e) Check that there is no fluid leakage caused by a break in the diaphragm.
(f) Connect the vacuum hose.
(g) Engage the clamp to install the vacuum hose.
